There is nothing to be happy about being a bounty hunter when you get cheated 9 out if 10 times with your hard work. If you want to continue as bounty hunter then make yourself better with analyzing so you can avoid more scam and useless projects than before and don't forget time is most valuable thing than anything.
9 out 10 bounties being unsuccesful - is this your experience? Even if analizing campaign to join, are you sure it will bring yo money? So far only Bitcoins is thing that grows. I came to this long time ago - bounties with payment in bitcoin are the only one worth participating. Other campaings are lotteries.
